On the Fox News show “Objectified”, Mark Cuban announced that if he were to run for president in 2020, he would run as a Republican and primary Donald Trump. Although he hasn’t decided, he’s been contemplating it for quite sometime. He noted that if his wife was down for it, then he might just do it. 
Cuban supported trump early in the 2016 race, but then backed Hillary after he felt Trump wasn’t being serious. After Mark Cuban appearance on Fox, Steve Bannon left a message for him stating, “No way he will win as a Republican”. You can hear them screaming now “He votes for Hillary”!
